Dear Professor,
I understand you are higher up than I am, and I completely get that you have so much more knowledge than I do about writing and that is a fact. But I don't necessarily agree that you should put me down for my writing to my face and make me upset about the things I am passionate about. You may not have the same opinions as me, but this doesn't mean that what I write and what I believe in is bad and is wrong.
Many other professors criticize, and that is completely okay. Without that, the aspiring writers out there in the world would never get better, and they would never expand their horizons out of their comfort zones in order to try out new types of writing and create new world's for themselves. This is what a professor should do. But they should also encourage and support what their students do and what they have the ability to accomplish. They should simply coach them and help them. Without this encouragement, there is less motivation and no self-confidence left in order to improve and better myself in what I am trying to accomplish.
Others may get heated and set out to prove their professors wrong, but some may not. It puts me down and makes me feel like there is no point to what I am doing and makes me want to give up writing for good. I mean, you said it was bad so why would I want to continue it? Shouldn't I go out and find something I am actually good at and could be successful with? Maybe I should, but I won't. I'm not going to give up.
I hope day you can read a piece of my writing that is worthy to your eyes and you take back some of the things you have said. I hope you can realize how hard I am working to make not only you, but all of the other people in the world who enjoy literature as much as I do, happy. Until that day comes, I will continue to read and expand my thoughts on writing. I will continue to better myself, but I will also have the thought in my head that I am not good enough to write. I hope and pray you don't put this thought into any of your future students' heads. I hope you learn to encourage and be proud of your writings and understand that not everyone is on the same level, but everyone is gradually improving day by day. I hope you can one day be proud that I was your student.
-Your Student
